5×3 = 15
7×3 = 21
Even numbers between 15 and 21:
16, 18, 20
Square Number: 16
Square Root of 16 = 4
Did that help cos I didn’t really get the question…

greater than 5 x 3, that is greater than 15
less than 7 x 3, that is less than 21
a square number between 15 and 21 can only be 16 (4 x 4)

16. 5*3=15, 7*3=21. So you’re left with 16, 18, and 20 as prime numbers. 4*4=16.
